Application :t1ec1-ll'u1y 11, 1919. serial No. 310,022.

To all whom it may concern:

' Be it known that li, VICTOR itl. SCHNEIDER, a citizen of the United tates, and resident of Aurora township, in 'the county of Florence and State of Wisconsin, have invented new and useful improvements in Screwdrivers, of which the following is a description, reference being had to the accompanying drawings, which are a part of this specification.

The present invention relates to certain new and useful improvements in tools and refers more particularly to a combination tool or screw driver.

@ne object of the presentinvention is to provide a combination screw driver which will present a broad working edge or bit for "use in connection with heavy screws or the like, or which may be operated to present a working edge or bit capable of use in connection with small screws or the like.

lnother object of this invention is to provide a combination .tool of the class described which will be of simple construction, efficient in operation and practical from every standpoint of view.

1li still further object of this linvention is to proyide a combination tool of the class described in which the various parts thereof are readily accessible.

Withthe above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as comewithin the scope of the claims.

ln the accompanying drawing, ll have illustrated one complete example of my in` vention constructed according to the best mode l have so far devised for the practical application of the principles thereof, and in which:

vlfigure 1 is a view taken longitudinally Y through my tool on the line 1-4-1 of llig. Q,

titl.

parts being in elevation and parts in section. Fig. 2 is a view similar to lFig. 1 taken f Fig. 3 is a transverse sectional view taken i through the handle of my tool on the line 3 3 of Fig. 1, and

lFig. t is a transverse sectional'view taken on the line 1-4 of liig. 1.

Referring now more particularly to thc accompanying drawing, 5 designates the inner portion of a two-part handle which is hollow throughout the major portion of its length as at 6, and has its eXtreme inner end reduced and threaded as at 7 to receive means for securing a tool 8 thereto, as will be later described; and 9 designates the outer end of the handle, also to belater described.

rllhe threaded boss 7 of the section 5 is centrally'bored as at 10, and hasforrned in its outer face a transverse slot or groove 11 adapted to receive a transverse rib 12 formed on the inner end of the tool 8, and adjacent a collar 13 also formed on said tool. rllhe tool 8 is rigidly -secured to the handle by means of a cap member v14: in threaded engagement with the boss 7 and having a lock `ing shoulder surrounding a central aperture therein'through which the tool 8 passes for impinging against the shoulder 13 to thus secure the rib 12 within its recess 11, see lFigs. 1 and 2.

'llhe tool 8 is centrally bored as at 15 and has slidably mounted therein a supplemental tool 8 which has its outer end 16 'tapered to correspond with the outer tapered end 17 of the tool 8,-said tools 8 and 8 when in normal positiomhaving their outer ends in the position depicted in lFigs. 1land 2 to thus present a broad working edge especially adapted for use in connection with large screws or the like. The inner end of the tool 8 is disposed within the hollow portion @of the section 5 and has formed on the extreme end thereof an enlargement or knob 18 slidably mounted within the central bore of a sleeve 19 which has projecting therefrom a rod or shank portion 20, to be later described. 1

rlFhe bore or hollow portion 6 of the section 5 is closed at its outer end by means of a anged nut 21 adapted to be locked in adjusted position by means ofa screw pin 22 and it is also provided with a central aperture 23 in which a portion of the rod 20 is journaled. lFormed in the inner peripheral wall of the handle section 5 is a guide slot 211 adapted to slidably receive a pin Q5 carried by the end 18 of the tool 8. The pin 25' passes throughna. spiral groove 26 formed in the tubular sleeve 19 and prevents therotation of the tool 8 when the sleeve 19 is rotated, by the means now to be described.

iat

The rod 20 has formed therein medially of, its ends an elongated opening or slot 27 through which passes a dowel pin 28 carried by the inner end of the handle section 9 which construction permits the partial sliding movement of the rod with respect to the section 9, but retains the same against rota-l The section 9 is also hollowT or tion. counter-bored as at 29 and has formed therein near its outer end a pair of alined openings 30, for convenience in inserting a dowel pin 31 in the outer end of the rod 20 for confining an extensile spring 32 between a washer 33 carried by theouter end of the rod 20 and the inner wall of the member 9. The recess 29 is inclosed by means of a plug or other suitable means 34, as best shown inFigs. 1 and 2.

- The inner end of the section 9 carries astud 34 -adaptedto selectively engage in a plurality of recesses l35 formed in the outer face of the flan ed nut 21 whereby the sec: tion 9 is norma y held from rotation with respect to the handle section 5. When it is desired to use a screw driver or tool having a small bit, the section 9 is drawn away from the section 5 and the flanged nut carried thereby compressing the spring 29 and disengaging the stud 34 from its recess 35, and the section 9is then revolved in a clockwise "direction, rotating with it the tubular sleeve I19. When the sleeve 19 is revolved in a l clockwise direction, the pin 25 will ride along the spiral groove-26, andas thevsame is held from rotation by reason of its engagement with the slot 24, the same will be moved to the right with reference to Figs.

l and 2 proj ectingthe end of the tool 8 outwardly of the end of the tool 8 as depicted by dotted lines. When'the tool 8 is in its extended position the section 9 is allowed'to be drawn inwardly under action of its spring 32 so that the stud 34 will engage the adjacent recess` 35 and thus permit the ready operation of the toolS will be obvious.

To move the tool 8 back to its normal position the action is the reverse tov that just ta blade carried bythe andle and norma ly providing the other blade with a single `workingedge ofone lsize, and means whereby said supplementary blade may beextended beyond the other blade to provide a smaller working edge independent of said other blade.
